Cedar shingles can be an attractive and functional material for siding. Cedar is naturally weather resistant, making it an ideal natural building material for shingles. When you find damage to a single shingle on your siding, you can replace or repair it without having to remove or disturb the rest of the shingles. It is important to repair shingles that become damaged to prevent damage to your home and further damage to the surrounding shingles.
Identify any damaged shingles that are in need of repair.
Position the chisel blade against the bottom edge in the centre of the shingle. Tap the handle with a mallet to split the shingle.
Slide the flat bar underneath the split shingle. Tap the end of the flat bar with a mallet to bend over or break off the nail that holds the shingle in place.
Pull the damaged shingle from the siding. Slide the flat bar up into the opening, and bend over or break off any remaining nails.
Insert a replacement shingle in place of the removed shingle.
Nail through the bottom of the shingle into the exterior of the home to secure the shingle in place. Space the nail 1 to 2 inches up from the bottom end of the shingle. Drive a second nail through the bottom of the shingle above the replacement shingle.
Set the nails approximately 1/16-inch below the surface of the shingles using a nail set.
Inspect your cedar shingles at least twice a year to keep your home's exterior in good condition.
Wear safety glasses when repairing cedar shingles.
